When deep-space listener Mara Okafor intercepts a transmission that shouldn’t exist, she becomes the only person alive who can decode it — humanity’s final message, or its first warning.
Racing a corporate fleet that wants the signal buried forever, Mara must decide how far she’ll go to hear the truth from the dark. As the decryption deepens, so does the cost: every answer opens a darker question, and the voice on the other end knows her name.
The Last Signal is a propulsive, deeply human thriller about the small choices that echo across light-years — and the courage it takes to finally answer.
